Question

The normal interest rate for an amount of two years is Rs. 50 and the compound interest is Rs 55. If both are the same interest rate, what is the amount?​

Answer 1

Answer:

125 ..... M...

Step-by-step explanation:

p × r × 2 /100 = 50 --(1)

difference in C.I & S.I = 55-50 = 5

p × r^2/100^2 = 5 --(2)

On deviding (2) by (1), we have

r/200 = 5/50 => r = 20%

from(1)

p × 20 × 2/100 = 50=> P = Rs 125
